hi im kinda bored so i figured i would do this and give someone an easy 10 points. w/ your answer i want yout o tell me how you did it
you have 2 liters of 4 molar HCL. how many liters of 2 molar NaOH will you need to run the reaction through to conpletion

I dunno if this is right but I used M1 x V1 = M2 V2. It's probably not right because you are using different substances but I got 4 L of 2 molar NaOH.
(2L (4 M HCL) ) / 2 M = 4 L

You would need 4 liters because in the reaction
HCL + NaOH ---> NaCL + HOH (H2O)
The species in the reaction have a 1:1 molar concentration, therefore, if you have 2 liters of 4 molar HCL, you would form 8 mol of NaCL. Since the molar concentrations are 1:1 and this is not limiting reactant in this equation (at least not from the data you provided) then there would need to be an equal volume * concentration of NaOH to react completely with the HCL. Therefore, you would need 4 L of NaOH to react completely with the HCL.

The other answers of 4 liters are correct.
The reason why is that the reaction
HCl + NaOH --> NaCl + H20
In other words it takes on molecule of HCl to react with one molecule of NaOH. It would therefore take one mole of HCl to react with one more of NaOH.
So if the NaOH is half the strength as the HCl solution, it will take twice as much NaOH to completely react with all of the HCl.
This means you must use twice as many liters of NaOH solution as the 2 liters of HCl. So that gives you 2 x 2 liters = 4 liters.

are you sure you need so much SULTY water :-))) he he he (4 liters - 2 liters of 4 molar hcl - is 8 mols of HCL - the reaction is HCL+NaOH=NaCl+H2O - so one needs 8 mols of NaOH which is 4 liters)....
P.S. one more time - HCl and NaOH cost more than salty water - don't mix them :-))))

4 Liters (to obtain 8000 equivalents) is the answer
